ARTHUR S. BRONSON, OF EL BASO, TEXAS.

CONTAINER.

Specification of Letters Patent.

Patented June 14, 1921.

Application filed March 6, 1920. Serial No. 363,908.

To all whom it may concern Be it known that I, ARTHUR S. BRONSO1\I, a citizen of the United States, residing in El Paso, Texas, have invented new and useful Improvements in Containers, of whlch the following is a specification.

This invention relates to containers and to means for expelling the contents of the same. The object of the invention is to provide a container adapted to contain heavy fluids and greases, said container being pro.- vided with a movable follower and means for actuating the follower from the exterior of the container together with a discharge opening through which the contents will be expelled by the movement of the follower within the container.

The device is intended particularly as a substitute for the ordinary salve jar or box from which the contents are ordinarily rethe fingers therein. Such procedure is highly unsanitary and the present invention aims to correct the fault of containers of the type indicated.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawings, Figure 1 is a perspective view of one form of the container. Fig. 2 is a vertical sectional View.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing and more particularly to Figs. 1 and 2, 5

designates a cupneck extension 6 upon the top thereof. A spindle 7 is mounted to turn in the neck extension 6 and has a bearing at 8 upon the bottom of the on or jar. The lower portion of the spindle 7 is threaded as indicated at 9, for engagement with a follower 10 which fits snugly within the receptacle or container 5. Spindle 7 may be held against upward movement by a pin or washer 11. A closure cap 12 is slidably mounted upon the neck extension 6 and a spring 13 bears between the top of this cap and a thumb piece 14 upon 7. A vertical port 15 leads from the interior of the receptacle through the neck extension to the un-' derside of the top of thecap 12 and a lateral port 16 communicates with the port 15 and opens at the side of the neck extension.

By turning the spindle 7 through the medium of the thumb piece 14, upward movement may be imparted to the follower 10, to put a pressure upon the contents of the container; this pressure being exerted through the port 15 upon the under side of the cap 12 to move said cap against action of. the spring 13 to uncover the port 16 and to permit some of the contents of the container After the desired quantity has been obtained a reverse movement of the spindle 7 will relieve the pressure upon the contents of the container and the spring 13 will act to gradually move the cap 12 downwardly to cover port 16.

It will thus be seen that when not in use the contents of the container are protected from dust and dirt and that only the necessary amount is expelled at any given time, and this without the necessity of inserting the fingers in the container.

From the foregoing description it will be seen that simple and efficient means are herein provided for carrying out the invention but it is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention what I claim is In a the combination with a container, a neck extension thereon, a cap slidably mounted upon said neck extension, a threaded stem controllable from the exterior of the receptacle, a spring acting upon said closure cap and normally tending to close the same, a follower, there being a port leading from the interior of the receptacle through the the neck extension of the underside of the closure cap and a port opening at the side of said neck extension and adapted to be uncovered by the movement of the closure cap under the action of the pressure created within the container by the movement of the follower.

In testimony whereof I aflix my signature.
